After having just put up preorders yesterday, Capcom's Ryuusei no Rockman 3 site now has a page for the Ryuusei no Rockman Official Complete Works book. While only a small preview, this should give a pretty good idea of what's to fill the book's 170+ pages. The detail is pretty amazing.
Very sweet. Additionally there's also a page for another Capcom book releasing at the same time, the Ryuusei no Rockman 3 Ultimate Guide: Battle Block Box. This book will cover all of Ryuusei no Rockman 3's secrets and such. The book also comes with a Noised Card for the game's final boss.
